The driving motor 1130 is electrically connected to the main body PCB1180 typically through a female, male connector, or the like, not by soldering, but electrically coupled to the main body PCB1180 through a motor power supply spring made of a material having high conductivity.

The driving motor 1130 is provided with a motor spring pin 1131 having an anode and a cathode. The motor power supply spring 1133 preferably includes a motor spring main body 1133a wound in a coil shape and interference-fitted with the motor spring pin 1131, and a motor spring energizing member 1133b bent in a state of being extended from the motor spring main body 1133a and coupled to the driving motor receiving portion 1112 to be firmly and electrically coupled to the driving motor connecting portion 1182 of the main body PCB 1180.

On the other hand, as shown in fig. 12(b), the drive motor connecting portion 1182 of the main body PCB1180 is formed of a through-going PCB groove 1186b having a rectangular shape with a width slightly larger than the diameter of the motor power supply spring 1133, and a PCB groove neck 1186b having a width gradually reduced at the end of the PCB groove 1186a to be smaller than the diameter of the motor power supply spring 1133. Here, the driving motor connection part 1182 preferably includes: a PCB groove 1186a through which the body PCB1180 having a certain thickness passes and a coating region (coat) in which a certain width (for example, 2mm) of the upper side and the lower side of the PCB groove neck 1186b and a certain passing thickness are plated with gold plating having good conductivity and wear resistance.

With the above-described structure of the motor power supply spring 1133, as shown in fig. 12(b), the motor spring energizing member 1133b having an elastically bent shape is coupled to the PCB slot 1186a having a slightly long shape, and is firmly and continuously contacted with the PCB slot neck 1186b having a smaller diameter by an elastic force, thereby being stably electrically connected to the main body PCB 1180.

In the electrical connection, the present invention does not use the conventional means such as electrical soldering and female and male connectors, thereby improving the work efficiency and eliminating the harmful work environment that may occur due to soldering or the like.

The speed reducer 1140 reduces the rotational speed generated by the drive motor 1130, is supported by the speed reducer housing 1113, and is supported by the speed reducer bracket 1500.

The speed reducer unit 1140 preferably includes a first speed reducer 1143 coupled to the drive motor 1130 for rotation and a second speed reducer coupled to the first speed reducer 1143 for transmitting a rotational force to the motion converter unit 1150.

The first decelerating member 1143 includes: a first driving gear 1143b engaged with a motor gear (not shown) coupled to a rotation shaft of the driving motor 1130, a first shaft 1143a rotatably supporting the first driving gear 1143b, and a first driving gear 1145b coupled to the first shaft 1143a to rotate together with the first driving gear 1143b and to be engaged with the second reduction gear 1145. Here, the first shaft 1143a is rotatably coupled to the reducer bracket 1500.

The second speed reduction member 1145 preferably includes a second drive gear 1145b that meshes with the first drive gear 1145b to rotate, and a second shaft 1145a that rotatably supports the second drive gear 1145 b. The second shaft 1145a is preferably rotatably coupled to the reducer bracket 1500.

The motion converter 1150 is coupled to the converter accommodating portion 1114, converts the rotational motion transmitted from the speed reducer 1140 into a linear motion, is coupled to the bracket 1500 while moving in and out of the main body case 1110, and moves between an open position (see fig. 10a) at which the door 10 is opened and a lock position (see fig. 5a, 5b, 5c, and 10b) at which the door 10 is locked. In this process, the motion converter 1150 may also function to hold the locked position where the body case 1110 is firmly coupled to the bracket 1500, and also transmit kinetic energy to the key rack 1300, which is moved between an engagement position (see fig. 7b), which is a state where the door key 1700 is coupled to the key rack 1300 and is not separated and held in a supported state, and a separation position (see fig. 7a), which is a state where the door key 1700 is separated from the key rack 1300.

As shown in fig. 3 and 9, the motion converter 1150 preferably includes: a switching lever 1151 coupled to the second shaft 1145a to rotate on the same axis, a switching guide spring 1153 coupled to the switching slider 1155 to be fixed to the switching lever 1151 at a constant pitch for converting the rotational force of the switching lever 1151 into a linear motion and coupled to the outer peripheral side of the switching lever 1151, and a switching slider 1155 slidably moved between an open position and a lock position along with a switching unit receiving portion 1114 disposed in the longitudinal direction of the 'X' axis direction together with the switching guide spring 1153.

The motion converter 1150 further includes a shelf converter 1157 which is provided on one side of the converter slider 1155 and converts the linear motion of the converter slider 1155 into a rotational motion. The switching lever 1151 includes: a shift lever shaft hole 1151a formed in a shape corresponding to an end of the second shaft 1145a which is a coupling device including an interference fit and configured to be engaged with and shifted from the end of the second shaft 1145a, and a shift lever pin 1151b protruded on an outer circumferential side and configured to be rotatable in accordance with a spiral pitch of a shift guide spring 1153 coupled to the outer circumferential side.

With this configuration, when the switching lever 1151 rotates when the second shaft 1145a rotates, and the switching lever pin 1151b protruding to the outer circumferential side rotates with the rotation of the switching lever 1151, the switching lever 1151 firmly coupled to the second shaft 1145a rotates only, the switching lever pin 1151b rotates with the pitch of the switching guide spring 1153 fixedly coupled to the inner side of the switching slider 1155, and the switching slider 1155 is guided to slide by the switching portion housing portion 1114, so that the switching slider 1155 linearly moves in the 'X' axis direction.

The switching guide spring 1153 is coupled to the outer circumferential side of the switching lever 1151 in a state of being firmly fixed to the inside of the switching slider 1155 so as not to be rotated, and is wound in a coil shape with a constant pitch so that the switching lever pin 1151b is positioned between the constant pitches.

The conversion slider 1155 has a structure in which the upper side of a long, hollow hexahedron shape, for example, which moves along the axis 'X' in the conversion unit housing 1114. The conversion slider 1155 is preferably provided with: a slider main body 1155a having a hollow hexahedral shape at the center, an open/close position spring 1155c having a spring shape capable of detecting an open position and a lock position at a position corresponding to the open/close switch connection part 1183 of the main body PCB1180, an open/close spring hole 1155b to which the open/close position spring 1155c is coupled, a clamp spring coupling groove 1155f to which a plate-like clamp spring fixing part 1178a of the clamp return spring 1178 is coupled in the up-down direction, and a slide rack 1155e provided at the side in a rack shape and engaged with a rest rack switching pinion 1157b of the rest rack switching part 1157.

The rack switching member 1157 is preferably provided with: a rest conversion shaft 1157c rotatably coupled to the main body case 1110, a rest conversion rack 1157b protruded on an outer peripheral side extended from the rest conversion shaft 1157c and engaged with the slide rack 1155 to convert a linear motion of the slide rack 1155e into a rotational motion, and a rest cam post hole 1157a provided in a polygonal shape on the same 'Z' -direction rotational axis as the rest conversion shaft 1157c on an upper side.

With the structure of the motion converting part 1150, as shown in fig. 9, which will be described later, there is an advantage in that two operations, that is, one operation in which the door 10 is locked and opened by the locker 20 by one driving motor 1130 and the other operation in which the door key 1700 is locked and separated on the key rest 1300 can be simultaneously performed.

That is, a first movement to a first operation in which the door 10 is opened and locked and a second movement to a second operation in which the door key 1700 is separated and stuck on the key rest 1300 may be simultaneously performed by one power generated and transmitted by the driving motor 1130. In the prior art, the power supply of two motors altogether is included respectively for first motion and second motion demand, and its power consumption is big, and the structure is complicated, and the circuit is also complicated, and the accessory is also many, and economic cost is higher, difficult preparation, and the fault rate is high, nevertheless the utility model discloses these problems and defect can be solved.

Here, a process of driving the motor 1130 to transmit power to the conversion slider 1155 is described in detail according to an embodiment of the present invention.

First, power is inputted from the motor power supply spring 1133 of the driving motor 1130 of the main body PCB1180, and when the driving motor 1130 rotates, the rotational force of the driving motor 1130 transmits the rotational force to the transfer lever 1151 through the first driving gear 1143 b-the second driving gear 1145 b-the second shaft 1145a, which are not shown, of the motor gears. When the switching lever 1151 rotates, the switching lever pin 1151b rotates, and the switching lever pin 1151b pushes out the switching guide spring 1153 fixedly coupled to the switching slider 1155 at a constant pitch.

By the force pushing out the switching guide spring 1153, the switching slider 1155 accommodated in the switching section accommodating portion 1144 of the main body case 1110 is guided to slide in the 'X' axis direction, and moves between the open position and the lock position while moving the main body case 1110 and the slide through hole 1116 in and out. Such sensing information of the so-called open position and the lock position is formed by an open/close position spring 1155c which is coupled to an open/close spring hole 1155b of the switching slider 1155, protrudes toward the main body PCB1180, and is electrically contacted with the open/close switch connecting part 1183.

The open/close position spring 1155c has elastic force and good conductivity. The portion of the open-position spring 1155c that contacts the open-position switch connection portion 1183, i.e., the diameter of the open-position spring 1155c (see'd spring-upper' in fig. 12 (c)), is, as shown in fig. 12(c), wider than the PCB groove 1186b of the open-position switch connection portion 1183 (see 'Wslot' in fig. 12 (c)). However, the width of the PCB groove neck 1186b portion of the open-close switch connecting unit 1183 where the open-close position spring 1155c reaches the open position and the latched position ('Wcontack' in fig. 12 (c)) is smaller than the diameter of the open-close position spring 1155c ('d spring-upper' in fig. 12 (c)).

On the other hand, four areas of the edge of the open/close switch connecting part 1183 of the main body PCB1180, which is in contact with the open/close position spring 1155c, are provided with coating areas including gold plating (see 'coat 1-1', 'coat 1-2', 'coat 2-1' and 'coat 2-2' of fig. 12 (c)).

That is, even if the switching slide 1155 is slightly shaken while the open/close position spring 1155c moves along the open/close switch link 1183 which is slightly extended in the 'X' axis direction, the width of the open/close switch link 1173 is larger than the diameter of the open/close position spring 1155c, and thus, a signal cannot be transmitted to the main body PCB 1180.

However, in the open position, even if the switch slider 1155 is slightly shaken, the open position spring 1155c having a resilient force is deformed and contacts both of the coating regions (see 'coat 2-1' and 'coat 2-2' of fig. 12 (c)) which are not electrically connected to the two open/close switch connecting portions 1183, so that a signal that the switch slider 1155 reaches the open position can be transmitted to the main body PCB 1180. By the signal, the main body PCB1180 is controlled to stop the operation of the driving motor 1130, and the 'OPEN (OPEN)' is displayed on the display portion 1383 of the shelf PCB 1380.

In the locked position, the two coating areas that are not electrically connected (see 'coat 2-1' and 'coat 2-2' of fig. 12 (c)) are also contacted by the open/close position spring 1155c, thereby signaling the main body PCB1180 that the switch slider 1155 has reached the locked position. By the signal, the main body PCB1180 is controlled to stop the driving motor 1130, and the 'CLOSE (CLOSE)' is displayed on the display portion 1383 of the shelf PCB 1380.

That is, a pair of coating regions (for example, a pair of 'coat 1-1 and coat 1-2' or a pair of 'coat 2-1 and coat 2-2') located on the left and right sides of the open/close position spring 1155c are in contact, and the open position and the lock position are detected by the open/close position spring 1155 c.

The open-close position spring 1155c is a structure provided so as to gradually increase the outer diameter toward the upper side (see an enlarged view of fig. 12 and section d-d). That is, the outer diameter of the upper side is'd spring-upper', the portion coupled to the conversion slider 1155 and the lower outer diameter approximately to the central portion are'd spring-lower', so that the outer diameter of the spring coil is gradually increased from the lower outer diameter to the upper outer diameter.

The structure is such that as shown in section d-d, the open and closed position spring 1155c is positioned at the PCB groove neck 1186b and is slightly deformed obliquely by the force of the direction of movement of the slider 1155 (see angle 'k' to 'k 2' of fig. 12, which is an axis inclined with the vertical axis of 'section d-d', i.e., 'k 1' and 'kO' as the center), more contact surface of the wound coil of the open and closed position spring 1155c can be effectively contacted to the coated region ('coat 1-1' and 'coat 1-2' are in the locked position, 'coat 2-1' and 'coat 2-2' are simultaneously contacted in the open position, respectively), thereby obtaining the effect of making electrical connection easier.

Through the structure, in the process that the conversion slider 1155 moves at the locking position and the opening position, even if the conversion slider 1155 and the like slightly vibrate and shake in movement, the main body PCB1180 can stably detect the operation state of the conversion slider 1155 and stably and effectively transmit the detected signal.

The bracket sensing part 1160 detects whether the door 10 reaches the locking position. The bracket sensing portion 1160 is provided with: the lock includes a sensing arm 1163 protruding from the lock body 1100 as a rotational movement reference to determine whether or not the sensing arm receiving portion 1540 provided in the bracket 1500 is in contact with the sensing arm hinge 1163a of the sensing arm engagement cam 1541, a sensing support member 1161 supported by the bracket sensing portion receiving portion 1115 of the lock body 1100, and a sensing spring 1165 having one side elastically received in a sensing spring receiving groove 1161a of the sensing support member 1161 to elastically press the sensing arm 1163.

The induction spring 1154 is preferably provided with: a coil-shaped reaction spring main body 1165a which is electrically conductive and is housed in the reaction spring housing groove 1161 a; a contact member accommodating part 1184a and a contact member accommodating part 1184a, which extend from one side of the reaction spring main body 1165a and are combined with the reaction arm 1163 to provide the elastic force of the reaction spring main body 1165a, and are combined with the reaction arm 1163 to provide the information of the position where the door 10 is locked when the reaction arm 1163 is not contacted with the bracket 1500 (the state where the elastic force of the reaction spring 1165 does not press the reaction arm 1163 against the contact member accommodating part 1184a of the reaction spring 1160 and is contacted with the main body PCB1180, see fig. 11b), and which judge that the door 10 is not locked when the reaction arm 1163 is not contacted with the bracket 1500 (the state where the reaction arm 1163 is not contacted with the bracket 1500 to apply pressure force); and an induction spring energizing part 1165c which is extended and bent from the other side of the main body 1165a to be electrically connected to the induction energizing part receiving part 1184b of the main body PCB1180 and has elastic force and is firmly supported.

The structure of the induction spring energizing part 1165c coupled to the induction energizing part receiving part 1184b of the main PCB1180 is the same as the structure of the motor spring energizing part 1133b coupled to the driving motor connecting part 1182, and thus, detailed description thereof is omitted.

The operation of the carrier sensing part 1160 having such a structure will be described in detail with reference to fig. 11a and 11 b.

First, fig. 11b shows a state where the sensor arm 1163 is elastically pressed by the sensor spring 1165 in a state where the door 10 is opened, and the sensor arm hinge 1163a is rotated with the elastic pressing force. At this time, the sensing spring switch contact member 1165b of the sensing spring 1165 contacts the coating area (coat) of the contact member receiving portion 1184a, and it is determined that the door 10 is not located at the locking position on the main body PCB1180 because the sensing arm 1163 is not located on the bracket 1500.

When the user closes the door 10, the sensing arm 1163 is received in the sensing arm receiving portion 1540 of the bracket 1500, and the force of contact with the sensing arm engaging cam 1541, i.e., the contact force, exceeds the elastic force of the sensing spring 1165 to elastically press the sensing arm 1163, so that the sensing arm 1163 rotates with respect to the sensing arm hinge 1163 a. The sensing spring switch contact part 1165b of the sensing spring 1165 is rotated along with the sensing arm 1163, and does not contact the coating area (coat) of the contact part receiving part 1184a, and the sensing arm 1163 is located on the bracket 1500, and it is determined that the door 10 is at the locking position on the main body PCB 1180.

With this structure of the bracket sensing portion 1160, it is possible to confirm and determine whether or not the door 10 is located at the lock position, and to perform control.

As shown in fig. 3, 5c, 10a, and 10b, the door clip 1170 includes: a clamp body 1171 in the shape of a quadrilateral plate; a clip engaging portion 1173 caught on the clip engaging member 1520 of the bracket 1500 is bent upward from one side end portion of the clip main body 1171; bent upward from the other side end of the clip main body 1171 to be caught on the clip catching ridge 1120a of the main body cover 1120 and contacted to the clip skirt 1177 of the clip spring elastic member 1178b which provides the elastic pressing force of the clip return spring 1178; the clip engagement portion 1173 and the clip skirt 1177 of the clip main body 1171 are formed to protrude toward the outer peripheral side toward the intermediate region on the other side of the non-bent region, and are rotatably supported by the clip hinge 1175 on the hinge housing portion 1155d of the switch slider 1155.

The clip return spring 1178 is engaged with the clip spring engaging groove 1155f of the switching slider 1155, and provides an elastic force to the clip skirt 1177 of the clip engaging portion 1173 so that the clip engaging portion 1173 is not caught by the clip engaging portion 1173 of the cradle 1500, and stably receives and supports the switching lever 1151 at the center.

The clip return spring 1178 is preferably provided with: a clip spring fixing member 1178a having a rectangular plate-like shape and both end portions coupled to the clip spring coupling grooves 1155f, a clip spring through hole 1178c formed through the center of the clip spring fixing member 1178a to support the switching lever 1151, and a clip spring elastic member 1178b extending from the clip spring fixing member 1178a and bent to press the clip skirt 1177 to elastically press the clip skirt 1177 to a unclamping position where the clip skirt 1177 is not caught by the clip catching member 1520 of the cradle 1500.

Further, the force acting on the clip return spring 1178 and the clip engaging portion 1173 is not in the vertical 'X' axis direction, which is the heavy direction, but in the left-right direction, and the locking position can be maintained with a small force without considering the self-weight of the clip engaging portion 1173 (see 'locking' of fig. 10 b).

With this structure, a process of the conversion slider 1155 operating between a locked position where it is not easily separated from the cradle 1500 and an unlocked position where the conversion slider 1155 is easily separated from the cradle 1500 (see 'UNCLAMPING' of fig. 10) will be described in detail below with reference to fig. 10a and 10 b.

That is, the locking position and the opening position refer to a position where the door is opened and closed on the storage cabinet, and the locking position refers to a position where the door is closed, and whether the door is separated in a direction of the plate surface on the storage cabinet. That is, the locking position is a preventive effect for putting a tool between the gap of the bracket and the locking body to detach or destroy the door from the locker. In this position, the plate surfaces of the clip main body 1171 are in contact with the clip engaging member 1520 and the cam sliding through hole 1116, and even if the key rest 1300 is grasped and pulled by an external force in a direction to open the door 10, the plate surfaces are not moved outward by the contact, and the locked position can be maintained.

First, the state of fig. 10a shows a state where the conversion slider 1155 is not close to the bracket 1500 and the door 10 is opened. At this time, when the elastic pressing force of the clip return spring 1178 is applied to the back of the side of the clip engaging portion 1173 of the door clip 1170 so that the clip engaging portion 1173 faces upward around the clip hinge 1175 and the clip skirt 1177 opposite to the side around the clip engaging portion 1173 and the clip hinge 1175 is lowered downward like a seesaw and enters and exits the slider accommodating portion 1530 of the bracket 1500, the clip skirt 1177 is not caught on the clip engaging member 1520.

When the switch slider 1155 moves forward to the lock position as shown in fig. 10b, if the force applied by the clip engaging portion 1173 contacting the clip engaging ridge 1120a of the main body cover 1120 acts in the positive (+) X 'axis direction, the contact pressure force of the clip engaging ridge 1120a exceeds the elastic pressure force of the clip return spring 1178 acting on the clip engaging portion 1173 in the negative (-) X' axis direction, and the clip engaging portion 1173 rotates clockwise about the clip hinge 1175. By this seesaw action accompanying the clockwise rotation, the clip skirt 1177 located on the left side with respect to the clip hinge 1175 is raised clockwise. By this action, even if an inappropriate external force (force forcibly acting between the bracket 1500 and the lock body 1100) acts in the direction of the 'X' axis, the skirt 1177 of the door clip 1170 attached to the body of the door 10 is caught by the clip catching ridge 1120a of the bracket 1500, and the door 10 is not pulled open, so that the door 10 is completely locked, thereby improving the safety of opening and closing the door 10, and preventing the door 10 from being improperly opened and closed (for example, the door 10 is forcibly opened at the locked position, and the contents inside the locker 20 are stolen, etc.)

When the conversion slider 1155 moves from the locked position to the open position, the pressure applied when the clip skirt 1177 contacts the clip engagement ridge 1120a gradually decreases and disappears, the elastic force of the clip return spring 1178 acts on the clip skirt 1177 to rise upward, and the clip engagement portion 1173 moves together with the conversion slider 1155 without being caught by the clip engagement ridge 1120a in the process that the clip engagement portion 1173 moves downward to the open position by the seesaw action.

Another embodiment of the process of moving between the locked and unlocked positions is illustrated in fig. 13a and 13 b. The other portions are substantially the same as the above-described example, except that a clip return magnet 2178 and a clip position resilient member 2179 are provided instead of the clip return spring.

With this structure, as shown in fig. 13a, the clip main body 1171 of the door clip 1170 is in a state where the clip return magnet 2178 pulls the clip main body 1171 downward in the unlock position. The clip position elastic member 2179 is in an extended state without contacting the clip skirt 1177 to be elastically deformed (the extended length in this case is shown in 'L1' of fig. 13 a).

Then, when the switch slider (2155) is moved, the clip skirt 1177 is pressed against the clip position elastic member 2179 to elastically deform the clip position elastic member 2179 (see 'L2' of fig. 13 b), and by these elastic deformation forces, the door clip 1170 is moved in the negative (-) Z-axis direction centering on the clip hinge 1175, such as a seesaw action. Then, the clip engaging portion 1173 is engaged with the clip engaging member 1520, and is kept locked even if an external force is applied.

Here, it is preferable that a magnet including a steel plate through which the door clip 1170 or the clip main body 1171 can generate a magnetic force by a magnet is included. For example, clip return magnet 1178 may be configured with one or two magnets 3mm in diameter and 3mm in length. With the above structure, the door clip 1170 can be stably operated between the locked position and the unlocked position by its own weight or the like in a tilted or horizontal state.

On the other hand, as shown in fig. 12 and the middle, the means for electrically connecting the main body PCB1180 to supply power or transmit signals may be further, stably and effectively electrically connected by the motor power supply spring 1133 and the driving motor connecting portion 1182, the induction spring 1165 and the contact member receiving portion 1184a and the induction energizing member receiving portion 1184b, and the open/close position spring 1155c and the open/close switch connecting portion 1183, which are made of a material having excellent conductivity and capable of stably maintaining elasticity and a deformed state.

Coating regions (coat, coat1-1, etc.) are appropriately provided around the housing portion to the

connection portions

1181, 1182, 1183, 1184, 1185 formed through the body PCB1180 so as to be electrically connected to each other, as required, thereby enhancing wear resistance against wear caused by electrical connection and contact with the spring. Here, the reference numeral '1181' is a region where the battery power supply housed in the battery housing 1111 and the main body 1180 can be electrically connected.

That is, according to these structures, the electric signal or power input means is formed by the electric wire and/or the sensor and/or the Printed Circuit Board (PCB) in the prior art, and the electric connection is formed by the connector and/or the soldering, but the present invention prevents the problems of damage and pollution of the working environment caused by the soldering and the like by supplying and/or transmitting and receiving the electric signal using the coil or the spring-shaped material having excellent conductivity and elasticity, instead of the connector and/or the soldering structure, and solves the problems of the complicated circuit structure and the like of the connector connection and the like.

The key rack 1300 couples the lock body 1100 coupled to the inside of the door 10 to the door 10, and supports the door key 1700. After the key rack 1300 determines whether or not the door key 1700 is supported and coupled to the door key support arm 1311, the ID of the door key 1700 is matched with the ID of the door 10, and the door key 1700 is moved between an engagement position (see fig. 7b) where it cannot be separated from the door key support arm 1311 and a separable position (see fig. 7 a). As described above, the operation of the disengagement position and the engagement position is performed simultaneously with the operation of the lock position and the unlock position by the operation of the driving motor 1130, which is one rotational force.

The key rack 1300 includes: a shelf main body 1310 which is coupled to the lock main body 1100, penetrates the door 10, protrudes from a through hole (not shown) of the door 10, bends and extends, forms a door key supporting arm 1311 capable of supporting a space of the door key 1700 between plate surfaces of the door 10, and opens outward in the 'Z' axis direction to support and accommodate the components; and a shelf cover 1320 for opening and closing the opened shelf main body 1310.

Preferably, the key rack 1300 includes: a door key engagement section 1330 described later; a shelf cam 1340; a door key grounding spring 1350; a connecting pin 1360; a shelf inner fixing portion 1370; a shelf PCB 1380; rest fixture 1390.

The material of the parts constituting the key rack 1300 is preferably formed of synthetic resin except for the portions (rack fixing member steel, etc.) to be firmly coupled to the portions (door key grounding spring, connector pin, rack PCB, etc.) to be electrically connected.

As shown in fig. 6a, the rack main body 1310 preferably includes: shelf cover coupling holes 1310a through which coupling means (not shown) such as ribs and bolts for coupling and fixing the shelf cover 1320 are supported or penetrated, and which protrude from the shelf cover 1320; door key engaging portion hinge shafts 1312 and 1312 which are protruded from the periphery and serve as supporting points for operation when the door key engaging portion 1330 operates in a seesaw type; a plurality of connector pin holes 1313 and provided therethrough for coupling connector pins 1360 that can be electrically connected to body PCB1180 and/or door key 1700; a shelf fixing member 1390 combined with a coupling means including a bolt to combine the lock body 1100 and the key shelf 1300 is combined with a coupling member hole 1314 and; a grounding spring hole 1315 provided through the door key resting arm 1311 side so that a projecting portion of the door key grounding spring 1350, i.e., the grounding spring projection 1352, projects outward; a door key engaging portion hole 1316 formed through the door key placement arm 1311 to allow the hook 1332 to enter and exit and to engage with the door key 1700; the catch 1332, which may rotate in conjunction with the shelf cam 1340, rests in the shelf cam hole 1317.

The shelf cover 1320 opens and closes the open region of the shelf main body 1310, and is exposed to the outermost side in the 'Z' axis direction, so that a part of the external appearance is formed together with the shelf main body 1310.

The shelf cover 1320 has a cover hole 1321 formed therethrough on the same axis as the shelf cam 1340, and a cover 1323 is detachably coupled to the cover hole 1321.

The cover 1323 includes a plurality of leg-shaped cover engagement portions 1325 detachably fixed to the cover hole 1321, the cover 1323 is formed of a transparent material, and the display portion 1383 of the rack PCB1380 is visible through the cover 1323. The cover 1323 is coupled to the cover hole 1321 on the same axis as the rest cam 1340, and the door 10 can be manually locked or unlocked by removing the cover 1323

For example, assuming a state in which the door 10 is locked, the door key 1700 is rested on the door key resting arm 1311, but the driving motor 1130 is not operated and the door 10 is not opened. At this time, according to the present invention, after the user removes the cover 1323 from the cover hole 1321, the user makes the JIG including the screwdriver, the allen key, and the like (see 'JIG' of fig. 7 c) pass through the cover hole 1321, the shelf inner side fixing portion 1370, the shelf PCB1380, and the door key engaging portion 1330 in order from the cam manual operation hole 1344 of the shelf cam 1340 and the same axis (see 'Z1' of fig. 7 c) in the direction of the 'Z' axis as shown in fig. 7c, and then sequentially engages with the cam manual operation hole 1344.

Then, when the jig is rotated, the rotational force is transmitted to the shelf cam 1340-door key engagement portion 1330 in the upward direction (the negative (-) direction of the 'Z' axis), the door key engagement portion 1330 is moved from the disengaged position to the engaged position, and the rotational force is transmitted to the shelf cam 1340-shelf switching member 1157-switching slider 1155 in the downward direction (the positive (+) direction of the 'Z' axis), so that the switching slider 1155 is moved from the locked position to the unlocked position, and the door clamp 1170 is also moved from the locked position to the unlocked position, and the door 10 is opened.

As described above, the present invention is inconvenient in that the door 10 can be broken or the structure of the door lock device 100 can be forcibly broken or damaged without a manual operation.

Of course, when the operation is performed by hand as described above, the display 1383 may sound an alarm unconditionally and the warning lamp may be turned on or off under the control of the main body PCB 1180.

The door key engagement section 1330 preferably includes: a body (not shown) having a long and slightly curved shape and; a locking hook 1332 provided at one side of the body and protruding outward, for locking or releasing the locking of the locking hole 1316 of the door key 1700 with the locking hook receiving groove 1790 of the door key 1700; an upper cam part 1343 provided at the other side of the body and varying in height ('Z' axis direction) in conjunction with the rotation of the shelf cam 1340, so that the engaging hook 1332 can be inserted into and removed from the cam contact part 1331 of the door key engaging part hole 1316; and an engaging hinge shaft 1333 coupled to the door key engaging part hinge shaft 1312 to serve as a supporting point of a seesaw movement in a process that the engaging hook 1332 performs a seesaw movement into and out of the door key engaging part hole 1316 according to a change in a rotational height of the shelf cam 1340.

The door key engagement portion 1330 preferably further includes: and an engaging return spring 1334 coupled to the body of the door key engaging portion 1330 between the engaging hinge shaft 1333 and the cam contact portion 1331 facing the engaging hook 1332, the engaging hinge shaft 1333 and the cam contact portion 1331 in the 'Z' axis direction, for elastically pressing the door key engaging portion 1330 to a separated position, thereby preventing the engaging hook 1332 of the door key engaging portion 1330 from protruding from the plate surface of the door key resting arm 1311.

The strength and distance by which the door key 1700 is caught and separated on the key rest 1300 by such a structure of the door key catching portion 1330, etc. will be described in detail below with reference to fig. 7a and 9.

First, the force (see 'Fcam' of fig. 9) that lifts the cam contact portion 1331 in the negative (-) Z 'axis direction, which acts as the height of the shelf cam 1340 increases as it contacts the cam contact portion 1331 of the door key engagement portion 1330, acts as a force (see' Fhook 'of fig. 9) that presses the engagement hook 1332 in the positive (+) Z' axis direction, to the right side of the center of the engagement hinge shaft 1333, which is the support point of the seesaw movement, so that the door key 1700 is held in the engaged position.

The effect of such lifting force 'Fcam' and pressing force 'Fhook' is related to the distance of the central axis (see 'Z1 "Z2" Z3' of fig. 7a) of the force (see 'L1 "L2" L3' of fig. 7a) at which the respective forces act from the center line axis (see 'ZO' of fig. 7a) of the snap hinge shaft 1333. That is, it is advantageous to make the distance 'L3' shorter than the distance 'L2', and therefore, in a range where deformation is possible, the distance 'L3' is set as short as possible as the distance 'L2'.

In this process, a force (see ' fcamp ' in fig. 9) opposing a force (see ' Fcam ' in fig. 9) lifting the cam contact portion 1331 in the negative (-) Z ' axis direction acts on the door key engagement portion 1330, canceling the lifted sum (Fcam).

In this regard, the present invention is to minimize the distance from the central axis of the catching hinge shaft 1333 to the catching return spring 1334 (see 'L1' of fig. 7a) in order to offset the lifting force 'Fcam' while maintaining the return elastic force of the catching return spring 1334 as described above, thereby stably catching and holding the door key 1700 in the catching position with a smaller force.

That is, with this structure, the engaging position and the disengaging position of the door key engaging portion 1330 can be operated with a small amount of force, and the structure is simple and convenient to use.

The rack cam 1340 is coupled to the hook 1332 of the key rack 1300 in the rack cam hole 1317 in the Z axis direction, is coupled to the rack switch member 1157 in the lower side (positive Z axis direction), and rotates to engage with the door key engagement portion 1330 in the upper side (negative Z axis direction).

The rack cam 1340 preferably includes: a cam body 1341 having a strip shape with the 'Z' axis direction as the longitudinal direction; a cam support 1342 having a shape corresponding to the shape of the rack cam support hole 1157a, and having a lower side coupled to the rack cam support hole 1157a of the rack switching member 1157 and engaged with and rotated; an upper cam member 1343 having an inclined contact surface with respect to the Z' axis direction and varying in height with the portion engaged on the upper side by rotation; a cam engaging cam 1345 rotatably supported in the engaging hook 1332 of the rack main body 1310 through the rack cam hole 1317; to engage a JIG (JIG) including a manually operable screwdriver, a cam manual operation hole 1344 of a certain depth such as a hexagonal section or the like is penetrated from the upper end along a rotational center axis (see 'Z7' of fig. 7a and 7 b).

The operation of the door key engagement portion 1330 and the shelf cam 1340 will be described in detail with reference to fig. 7a and 7 b.

First, fig. 7a shows a state where the switch slider 1155 is in the lock position and the door 10 is closed, and the height at which the rest cam 1340 and the door key engagement portion 1330 are engaged is shown as 'H1' in fig. 7 a. At this time, the door key engagement portion 1330 can separate the door key 1700 without protruding toward the plate surface of the door key placement arm 1311 by the force of the engagement return spring 1344, and the user can wear the door key 1700 on his wrist and keep it in a state where the door 10 is closed.

When the user rests and senses the door key 1700 on the door key resting arm 1311 and the driving motor 1130 rotates to rotate the resting rack cam 1340, the engagement height of the inclined surface of the upper cam member 1343 and the cam contact portion 1331 of the door key engaging portion 1330 becomes larger (see the difference between ' H1 ' and ' H2 ' in fig. 7a) as the upper cam member rotates, and the engagement height of the inclined surface of the upper cam member and the cam contact portion 1343 becomes larger, and preferably has an inclined shape, as shown in fig. 7b, the engagement height becomes higher in the negative (-) Z ' axis direction to be ' H2 '. Due to the height difference (H2-H1, height rise), the engaging hook 1332 can protrude from the plate surface of the door key rest arm 1311 by the seesaw operation of the door key engaging portion 1330 formed around the engaging hinge shaft 1333, and is lowered toward the engaging hook receiving groove 1790 of the door key 1700 to be engaged, whereby the door key 1700 is held in the engaging position. The door key 1700 is located at the above-mentioned engagement position, and the user can open the door 10 and take out or put in clothes or the like in the storage cabinet 20 in a state where the user cannot separate the door key 1700.

That is, the operation is performed at a driving force, i.e., the driving motor 1130, as described above, as shown in fig. 9.

For this, the related art requires two power sources, i.e., a first power source including a motor required for the movement of the open position and the locked position of the door 10 and a second power source including a motor required for the movement of the engaged position and the disengaged position of the door key 1700.

In contrast, the present invention can be implemented by moving the open position and the locked position of the door 10 and the engaging position and the disengaging position of the door key 1700 using one power source, as described above.

To this end, the utility model discloses a, the power supply including driving motor 1130 is one, and the power consumption reduces, and required accessory, circuit structure, sensor response structure etc. become fewly, and material cost, manufacturing cost etc. reduce, and the fault rate reduces to promote economic nature, efficiency and security etc..

The applicant has found that, in order to compare the consumption of the battery under the same condition, the results of the test of the two motors and the RF-type door key and the grounding mode of the present invention and the grounding mode described later are very fast, and the battery life is maintained by about three times or more when the present invention is operated as compared with the operation according to the prior art.

Door key grounding spring 1350 is a part protruding on grounding spring hole 1315 of door key resting arm 1311, electrically connected to door key 1700 resting on door key resting arm 1311, and transmits information of key ID part 1770 of resting door key 1700 and information that so-called door key 1700 is resting on door key resting arm 1311 to resting rack PCB1380 and main body PCB1180 through electrically connected connector pin 1360.

The door key grounding spring 1350 is made of the same material and has the same electrical characteristics as the motor power supply spring 1133, the open/close position spring 1155c, the inductive spring 1165, and the like, which are electrically connected to each other.

The door key grounding spring 1350 is shown in fig. 4 and 8, and includes: a coil-shaped grounding spring body 1351 combined to the connector pin 1360; a grounding spring protrusion 1352 which is elongated from the grounding spring main body 1351 and is convexly curved from the door key resting arm 1311 plate surface; grounding spring catches 1353 supported inside grounding spring holes 1315 extend from grounding spring protrusions 1352.

With this structure, when the door key 1700 is positioned on the door key resting arm 1311, the grounding part 1750 of the door key 1700 contacts and reads the information of the door key 1700 input in the key ID part 1770, and at the same time, provides information of the state in which the door key 1700 is resting on the door key resting arm 1311. The information is transmitted to body PCB1180 and shelf PCB1380 through connector pins 1360.

The present invention reads the information of door key 1700 by the contact method of electrical communication and connection through the electrical contact and the proximity contact of door key 1700 and door key grounding spring 1350, instead of communicating the information of door key 1700 by the commonly used RF (Radio Frequency) method as in the prior art.

That is, the RF system is a communication system using a frequency, and requires more power consumption for communication than the ground system, and the circuit is complicated, and the cost of the related parts is also large.

The utility model discloses a, to door key 1700's communication mode, different with prior art, be the structure that can adopt the ground connection mode, have that the required power consumptive also reduces by a wide margin of communication, the circuit is also simple, advantages such as accessory cost also reduces.

The connection of connector pin 1360 is as shown in fig. 4 and 8, enabling electrical connection and hence transmission and reception of signals between door key ground spring 1350 and/or shelf PCB1380 and body PCB 1180.

The connector pin 1360 is coupled to the plurality of connector pin holes 1313, and includes: upper pins 1361 and upper contact members 1361a provided on the upper side, i.e., on the shelf PCB1380 side, and electrically contactable with each other; a lower pin 1363 and a lower pin 1363a provided with a lower contact member 1363a which can be electrically contacted with the lower side, i.e., the side of the body PCB 1180; and upper and lower connection springs 1365 which are coupled with the upper and

lower pins

1361 and 1363, respectively, to electrically connect the upper and

lower pins

1361 and 1363, and provide elastic force to firmly contact and hold the upper and

lower pins

1361 and 1363 to the rest PCB1380 and the body PCB 1180.

The center of each of the upper and

lower pins

1361, 1363 includes upper and lower

engaging cams

1361b, 1363b that project outward from the other regions.

By the structure, the lock body 1100 and the key rest 1300 can be electrically powered by a simple assembly structure as described above without using wires or wires and female and male connectors and soldering as in the prior art.

The rack inner fixing portion 1370 preferably includes: shelf fixing parts 1390 combined with the connecting part hole 1314 of the shelf main body 1310; connector pins 1360 coupled to the connector pin holes 1313; a door key engaging portion 1330 coupled to the door key engaging portion hole 1316; a door key grounding spring 1350 and a door key grounding spring whose one side is combined with the grounding spring hole 1315 and the other side is combined with the upper pin 1361; shelf PCB1380, which is coupled to connector pin 1360 in combination with connector pin 1360, is firmly supported on shelf body 1310 by snap spring receiving member 1371. Therefore, in order to support the engaging return spring 1334 on the upper side, the shelf main body 1310 may be coupled by various known methods including a snap fastening method which generates a rattling noise in the process of being firmly supported and coupled.

The rack 1380 preferably includes: connector pin contact portions 1381 coupled to upper sides of the connector pins 1360 to be electrically connected; a display 1383 displaying the current operation state such as an 'OPEN (OPEN)' or 'locked (CLOSE)' state or an operation state.

The connector pin contact 1381 is the driving motor connecting portion 1182 of the main body PCB1180 as described above, and a coating region is provided around the through hole to make electrical contact with the lower pin 1363 more effective, and the electrical connection between the connector pin joint 1185 of the connector pin contact 1381 and the main body PCB1180 and the

pins

1361, 1363 is more effectively performed by the upper and lower connecting springs 1365 which electrically connect the upper pin 1361 and the lower pin 1363 and elastically press the upper pin 1361 and the lower pin 1363 toward the

respective PCBs

1180, 1380.

The bracket 1500 is coupled to the storage cabinet 20 side where the door 10 is provided, and locks the door 10 in the open/close position.

The bracket 1500 includes: a bracket body 1510 firmly coupled to the locker 20 by a coupling means including bolts; a slider housing portion 1530 provided on one side of the bracket body 1510, having a clip engaging member 1520 in which a conversion slider 1155 is protruded and housed at a lock position and a clip engaging portion 1173 can be engaged; the sensor arm receiving portion 1540 is provided on the other side of the carrier body 1510, and includes a sensor arm engaging projection 1541 for receiving and contacting the sensor arm 1163 of the carrier sensor 1160.

The door key 1700 is a means for the user to carry to open and close the door 10, and preferably includes: a key ID unit 1770 which is coupled to one side of the key body 1710 and which incorporates ID information of the locker 20 or the door 10 in which the user stores articles including clothes; a grounding part 1750 coupled to the other side of the key body 1710 and capable of grounding the door key grounding spring 1350 when the door key 1700 is seated on the door key seating arm 1311; the key cover 1730 is coupled to the key body 1710 to form an external appearance, and is engaged with the engaging hook receiving groove 1790 of the engaging hook 1332.

With the above-described structure, when the user places the door key 1700 on the key placement shelf, the user can grasp whether the ID of the door key 1700 matches that of the door 10 by the door key grounding spring 1350 electrically connected to the key ID part 1770. Also, information whether the door key 1700 is seated on the key seating stand 1300 can be grasped by the door key grounding spring 1350 electrically connected to the grounding part 1750.

Here, unexplained reference numeral 1184 denotes a bracket induction engagement portion, and includes a contact member receiving portion 1184a and an induction-powered member receiving portion 1184 b.

The operation of the door-lock apparatus 100 of the present invention having the above-described structure will be described in detail.

First, when power is inputted from the outside or power is supplied from a built-in battery, the main body PCB1180 and the rest 1380 are ready to operate.

When a user enters a plurality of utilization facilities, namely, a bathing pool, the user pays first, and after getting the door key 1700 to the administrator, the door key 1700 is placed on the key placement shelf 1300.

At this time, the door 10 may be in the open position or the locked position.

In the open position, the tray sensing part 1160 is in the open position, and thus the main body PCB1180 does not separately perform a process of opening the door 10, but a state in which the user puts articles including clothes into the locker 20 in a state in which the door 10 is opened, closes the door 10, and the tray sensing part 1160 waits for information that the door 10 is in the locked position. At this time, the user may put the door key 1700 on the key rest 1300, and confirm whether the ID information of the door 10 is identical on the main body PCB 1180.

However, since the door 10 is normally locked when the user first uses the door, it is preferable that the switch slider 1155 is located at the locked position, the open/close position spring 1155c is also located at the locked position, the clip locking portion 1173 is located at the clip position, the door key locking portion 1330 is located at the separated position, and the cradle sensing portion 1160 is also located at the locked position or in a state of detecting these positions, respectively.

When the user first puts the door key 1700 on the key placement frame 1300, the main body PCB1180 senses this, and determines that the user wants to open the door 10.

The information of the door key 1700 to be shelved is then communicated through the door key grounding spring 1350 electrically connected to the key ID part 1770 and the grounding part 1750 of the door key 1700, and the information is transferred to the shelf PCB1380 and/or the body PCB 1180. Based on the information transmitted and inputted, the main body PCB1180 determines whether the door key 1700 and the door lock apparatus 100 are identical or not.

When the judgment result is inconsistent, the display section 1383 blinks or finds an alarm sound, or displays inconsistent information to the user.

When it is determined that the information of the door key 1700 is identical to that of the door lock apparatus 100, the main body PCB1180 supplies power to the driving motor 1130 to rotate the driving motor 1130.

As the driving motor 1130 rotates, the rotational force is transmitted to the first speed reduction member 1143, the second speed reduction member 1145, and the switching lever 1151, and then the rotational motion is converted into a linear motion by the switching guide spring 1153 and the switching lever pin 1151b, and the switching slider 1155 moves to the slide through hole 1116 side through the slider accommodation portion 1530 in the positive (+) axial direction of the 'X'.

At the point of completion of the movement, the open and closed position spring 1155c contacts the coated areas on both sides of the open position of the PCB notch 1186b (see ` coat2-1 `, ` coat2-2 ` in FIG. 12 (c)), notifying the arrival of the open position. The main body PCB1180 recognizing that the open/close position spring 1155c reaches the open position controls the driving motor 1130 to stop operating.

During this movement, when the clip slightly moves from the locked position to the open position, the clip engagement portion 1173 is disengaged from the clip engagement member 1520 and is acted on by the elastic force of the clip return spring 1178, so that the clip skirt 1177 does not get caught on the clip engagement member 1520 while moving down toward the center of the switch slider 1155.

On the other hand, as shown in fig. 9, simultaneously with the linear movement of the switching slider 1155, the rack switching pinion 1157b engaged with the slide rack 1155e operates to rotate the rack switching member 1157. With the rotation of the rest switch member 1157, the rest cam 1340 engaged with the rest switch member 1157 rotates, the cam-shaped upper cam member 1343 inclined to the upper side of the rest cam 1340 rotates, and with the rotation of the upper cam member 1343, a height difference occurs due to the characteristics of the inclined cam member (see 'H1' and 'H2' of fig. 7b), and the cam contact portion 1331 of the door key engagement portion 1330 engaged therewith rises.

The engaging hook 1332 of the opposite side, which performs the seesaw movement with the engaging hinge shaft 1333 as a supporting point, is lowered by the rising of the cam contact portion 1331 of the door key engaging portion 1330. By the lowering, the engaging hook 1332 protrudes from the plate surface of the door key placing arm 1311, and engages with the engaging hook receiving groove 1790 of the door key 1700 placed between the plate surface of the door key arm 1311 and the plate surface of the door 10, and the door key 1700 is held at the engaging position where it is not separated from the key placing frame 1300.

The user can then open the door 10 to put articles including clothes into the storage cabinet 20, the door key 1700 does not need to be carried separately, and the door key 1700 is placed in the engaged position in a state where the key rest 1300 cannot be separated.

Then, when the user opens the door 10, the sensing spring 1165 of the tray sensing part 1160 is separated from the tray sensing arm engaging cam 1541, and contacts the contact member receiving part groove neck to provide the opening information of the door 10 to the main body PCB 1180.

When the door 10 is opened, the user can store the article in the storage cabinet 20, and when the door 10 is closed after all the articles are placed in the storage cabinet, the sensing arm 1163 of the tray sensing part 1160 is received in the sensing arm receiving part 1540 of the tray 1500 and comes into contact with the sensing arm engaging protrusion 1541 to perform the rotation motion, the sensing spring switch contact part 1165b combined with the sensing arm 1163 comes into contact with the contact part receiving part 1184a to transmit the information that the door 10 is located at the locking position to the main PCB 1180.

When the two kinds of information (here, information that the sensor arm 1163 is in the lock position and the door key 1700 is in the engagement position) are input and grasped by the main body PCB1180, the main body PCB1180 rotates the driving motor 1130 in the opposite direction to the above direction, so that the conversion slider 1155 moves from the open position to the lock position, and the door key engagement portion 1330 moves from the engagement position to the release position. As a result of the movement, when the signal indicating that the open/close position spring 1155c reaches the lock position is transmitted to the main body PCB1180, the rotation of the driving motor 1130 is stopped under the control of the main body PCB1180, and the display 1383 displays the lock state. The user then separates the door key 1700 in the separated position from the key rest 1300 and moves the door key 1700 while wearing it on the wrist.

Of course, in this process, the display 1383 may display the operation processes or the operation completion state under the control of the main body PCB1180, and the user may view the operation processes or the operation completion state through the external transparent cover 1323.

If the door key 1700 of the user is not in accordance with the information of the door 10 or the information of the door lock device 100, for example, and the rest cam 1340 is operated by hand, if the door key 1700 is not required to be in the key rest 1300 and the sensing arm 1163 is in the open position at the locked position, the remaining battery amount is less than 10%, the main body PCB1180 generates an alarm sound, alarm, or the like on the display 1383 of the rest PCB 1380.
